Files POSTed to an object fail to be assigned a file type

[stuartlewis]

When adding a file by POSTing it to the EM-IRI of an existing item in DSpace, the bitstream doesn't seem to be given a file type, so it classified as 'unknown'.

However, the same files added to the SWORD bundle, are given their correct file types.
